That's it exactly Peter...I believe it has already been a well established fact, that the o-rings are service items and at some point...the o-rings will need replaced...of course they will. all materials degrade over time, especially if they are carrying any sort of weight or are under some sort of stress...I haven't changed the o-rings on my deck as yet and don't expect to, for quite some time and the cost of replacements is minimal. A nice new, fresh set of rings, a few small adjustments and Bob's your uncle...I don't see any problem..the huge improvements to my deck outweigh the little cost of a new set of o-rings...As for them failing, there is six on each pylon and again I will point out, what are the chances of six o-rings per pylon, all failing together....next to nil...I've tried all kinds of materials for the o-rings, even trying our lasses hair bobbles..the NBR are by far the best option, for the stability, the damping factors and the shock absorbig effect...OK NBR rings with the fibre cor, is an interesting concept, but the cost is too high
